ICF-TABLE.

SPECIFICATION forming part of Letters Patent No. 742,585, dated October27, 1903.

Application filed May 16, 1903.

To all whom it may concern:

Be it known that I, THOMAS H. BUTLER, a citizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in Ice-Tables; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to mechanism for supporting cakes of ice, such asmanufactured in ice-machines, which have to be sawed into blocks forshipment bymeans of suitable cutting mechanism; and it consists in thenovel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure l is a vertical section through the ice-tableand the hydraulic cylinder for operating it, showing a side view view ofthe same, but shows the table horizontal.

A is a floor or platform provided with an opening a. B is a strong floorjoist or beam at one side of the said opening.

0 is the ice-table, and D represents hinges which connect one edge ofthe table with the joist B.

The table is normally supported level with the floor; but it may beturned on its hinges to raise or lower it, as'required.

The table is of any approved construction, and it is provided withprojecting end plates 0 near its hinges. These end plates are removable,being dropped into suitable holes or sockets in the table.

E is a hydraulic cylinder provided with a telescopic ram orpiston F,having its upper end pivoted to the under side of the table by a pin e.

G represents trunnions on the lower part of the cylinder E, which arejournaled in bearings g, supported by a suitable foundation under thetable. I

H is a flexible pipe through which water is admitted and let out. Thewater is supplied to the cylinder under pressure and is confierial No.157,358. (No model.)

trolled by a valve of any approved construc' tion.

By forming the ram in telescopic sections the pit wherein it works canbe made much shallower than when an ordinary ram is used.

I is the ice-chute below the level of the floor A.

The table is raised, as shown in Fig. 1, and a cake of ice is thenplaced on the end plates by meansof a crane, one side of the cakeresting against the table. The table is then lowered to the positionshown in Fig. 2 by letting a portion of the water out of the cylinder.The end plates are then removed, and the ice is sawed into convenientblocksfor shipment. The table is lowered to the position shown in dottedlines in Fig. 1, and the blocks of ice slide off its surface and passdown the icechute I into the packing or shipping chamber.

What I claim is- 1. The combination, with a floor or platform having anopening, of a pivoted ice-table working in said opening and having itsupper surface normally horizontal, means for supporting-the ice on thesaid table when the table is placed in an inclined position, a hydrauliccylinder pivotally supported under the table, and a ram or pistonsliding in said' cylinder and operatively engaging with the said table.

2. The combination, with a floor or platform having an opening, of apivoted ice-table working in said opening and having its upper surfacenormally horizontal, means for supporting the ice on the said table whenthe table is placed in an inclined position, a hydraulic cylinderpivotally supported under I the said table, and a telescopic ram orpiston sliding in the said cylinder and having its upper sectionoperatively engaging with the said table.

In testimony whereof I affiX .my signature in presence of two witnesses.
